Zipping up some butt joints on the corners of these 18ga stainless machine covers when I discovered a difference in the bead appearance due to my inconsistent torch angle. These get ground smooth so no biggie...but I thought this was a great illustration of how a slight deviation can be the difference between "slick" and "nipping the corner".

Notice one of these is not like the other?

Here's the straight in angle for the flat beads.

Here's the "lazy cause its like the 30th little bead" angle.

Just a few tiny degrees can make a pretty noticeable difference.

If ya want to weld like Roy...Step up your prop game, keep that angle consistent (both directions), and get comfy.

Car keys: 18ga 304 stainless sheet. 0.030' 308L filler for tack at open end.
1/16" 2%thor tungsten.
clear #12 cup
120 amps, 20% on, 25% bknd, 2.1 pps.

Those welds look good, the odd one out may have pointed out that your amps could be a tad lower just based on its colour, the other welds are good and your HAZ is great so there would be nothing in it it looks like the filler chilled the odd one a bit more. I could be wrong, wouldnt be the first time if you check with the wife she has a list....archive. :)
